Summary
Severe allergic reactions to natural rubber latex can occur unexpectedly, even with mild prior symptoms. Diagnosis can be challenging, and cross-reactivity with certain fruits is possible.
Area of Science:
- Immunology
- Occupational Health
Background:
- Immediate type hypersensitivity reactions to natural rubber latex (NRL) pose a significant health risk.
- Awareness of NRL allergy is crucial, particularly for healthcare professionals and individuals with frequent exposure.
Observation:
- Three cases of severe hypersensitivity to NRL are presented.
- One patient developed generalized urticaria and asthma due to airborne latex allergens after occupational exposure.
- Negative or weak IgE-RAST results were observed in patients with severe reactions.
Findings:
- Latex allergy diagnosis can be complex, with potential for severe reactions despite seemingly mild initial symptoms.
- Cross-reactivity between NRL and certain fruits (banana, avocado, kiwi) may occur.
- Airborne latex allergens can trigger severe systemic reactions in sensitized individuals.
Implications:
- Medical staff must be vigilant regarding potential severe adverse reactions to latex gloves in patients.
- Alternative glove materials like vinyl, Elastyren, or Tactylon should be considered for at-risk individuals.
- Further research into diagnostic methods and cross-reactivity patterns for latex allergy is warranted.
